For enabling Raspberry Pi 7 inch touchscreen I configured device tree according to the binding. However, when I compile it it gives me syntax error and FATAL ERROR: Unable to parse input tree. I have read many pages of website about device tree but g...
Dear team,We have a design with stm32mp157aac MPU, and we use MIPI DSI as the display interface to a device with 1280x720@60 RGB888, the PCLK is 74.25MHz, the DSI works at non-burst sync event video mode. But the image is flickering continously. Whe...
Hi there,I am trying to use the plasma-mobile enviroment as default in the x11 distro. I documented in detail everything in this issue (easy to reproduce): https://github.com/schnitzeltony/meta-qt5-extra/issues/73Can someone from ST look into this to...
I configured UART7 and USART3 to work with RTS in linux (for A7) - I generated the DTS and checked to use the correct pins (according to schematics) to make sure are mapped to the Arduino connector (UART7) amd RPI GPIO like connector The UART7 & USAR...
The hardware is STM32MP157C-DK2 board.1. We setup the test environment as below:We bridge the USB port and the Ethernet port in the ST.The throughput is about 270Mbit/sec(Limited by the usb to Ethernet convertor).2. Another test environment is:The ...
is stm32mp153 can start weston without gpu
I am going to extend some GPIO for 157 for keyboard, I found on EV board is a MCU of STM32L157 to implement, do you have any firmware information about this MCUSource code or I2C protocol, or have other similar chips
Hello.Is code for STM32MP157 is compatible for STM32MP153?I can't find description of this MPU in arm-trusted-firmware's device tree.
Hello,I am applying the second scenario of example openamp_tty_echo_wakeup.The scenario is to wake up and make the system run again from "MCU : running and MPU :Cstop".My question: When MPU goes in Cstop mode with the command "echo mem > /sys/power/s...
